Research

The lactocrine hypothesis, based on research from our laboratory, suggests that colostrum serves as a conduit for delivery of maternally-derived developmental signals in the neonate. Using the pig as a model system, studies demonstrate that lactocrine signaling shortly after birth affects both the developmental program and trajectory of porcine uterine and cervical tissues. My research goal is to better understand maternal programming of development by way of mother's milk during the neonatal period on long-term reproductive function in the adult pig.

Currently, research areas include:

1. Determining the long-term effects of nursing on adult uterine gene expression and protein secretion during the periattachment period of early pregnancy.
2. Investigating the effects of nursing and milk replacer feeding on neonatal small intestine development using quantitative PCR (qPCR) analysis.
3. Evaluating whether epigenetic changes are occurring in response to age and nursing from birth by monitoring (a) global uterine DNA methylation patterns as well as (b) DNA methylation of promotor regions of specific genes involved in neonatal uterine development.
